UNIT-l
Q.2 (a) What are the enhancements added to C++ apart from the object oriented features? (2.5) (b) Explain the need of default arguments. Write an interactive program for drawing chart
of marks scored by a studdht in different using default value parameters. (10)
Q.3 (a) What are the different types of parameter passing methods supported in C++?
Explain. (5)
(b) What are inline functions? Write an interactive program tp find the maximum of two
numbers using inline function. (7.5)
UNIT-II
Q.4 (a) What are the differences between structures and classes in C++? (2.5)
(b) Write a program for adding two vectors (which are objects of the class vector). Use
dynamic data members instead of arrays for storing vector elements. (7.5)
I
Q.5 (a) What are constructor and destructors? Explain how they differ from normal functions. (2.5) (b) Write a program to model time class using constructor. The data members are hour,
minute and second. Write functions to add two time values and display it. (10)
UNIT-III

in the definition of an overloaded binary operator? (2.5)
(b) Write a program to overload unary operator for processing counters. It should support
both upward and downwaidcounting. ' (10)
Q.7. (a) Whajt are the differences between access specifiers private and protected? (2,5)
(b) What are abstract classes? Write a program having student as an. abstract class and create derived classes like Engineering, Science, Medical, etc. from the student class. Create their objects and process them. (10)
UNIT-IV
Q.8 (a) What is a class template? Explain the syntax of a class template with suitable
examples. (5)
(b) What is function template? Write a function template for finding largest number in a
. given array. The array parameters must be of generic data types. (7.5)
Q.9 (a) Explain the various file stream classes needed for file manipulation. (5)
(b) Write an interactive program that accepts students score and prints the result to a
file. (7.5)
